Oil Change Interval:
Every 3,000 - 5,000 miles (4,800 - 8,000 km) or 3-6 months, using the recommended oil viscosity.
Air Filter Replacement:
Every 15,000 - 30,000 miles (24,000 - 48,000 km) or annually, or sooner if driving in dusty conditions.
Spark Plug Replacement:
Every 30,000 - 60,000 miles (48,000 - 96,000 km) depending on plug type (e.g., standard vs. platinum).
Timing Belt Replacement:
Crucial for interference engines like the 4G63. Recommended every 60,000 - 90,000 miles (96,000 - 144,000 km) or 5-7 years. Failure can cause catastrophic engine damage.
